Hi @Glen_Giffen ,
Changing DNS is a fairly common troubleshooting strategy, nothing to be nervous about. Let us know if you need any specific assistance!
Hi there, i managed to change the DNS server on my Samsung to dns.google and saved this setting. Unfortunately, it has made no difference and I still can’t reliably playback Qobuz via Roon ARC.
Wondering if this could be a Qobuz cache issue on the Roon Rock? Is there a way to clear the cache?
Hello @Glen_Giffen,
When using ARC with streaming services, a direct connection is made between the ARC app and the streaming service. This means the Roon Server is not involved in the playback process and does not cache any of the content.
Just to confirm, can we clarify the current behavior across your devices?
From what I understand:
- Qobuz is not working at all on the S22
- It plays a few songs but stops when switching on the S25
- And it’s working as expected on the tablet
Please let me know if that’s correct or if anything has changed.
I’ve added your latest findings to our internal ticket with the R&D team, and we’ll update you here as soon as we have more information to share.
Hi there,
Not quite correct, it doesn’t play back Qobuz reliably over the 5G network on either the S22 or S25 so that behaviour is device agnostic. It plays back reasoanbly reliably on all devices when connected to wi-fi.
It works across all devices lightening quick and reliably when playing back music stored on my local network drive on both the 5G and wi-fi.
Thanks,
Glen
Hello @Glen_Giffen,
Are you able to play songs directly from the Qobuz app in the same conditions when ARC returns the errors?
Hi @Glen_Giffen,
To summarize the details you’ve provided so far, the S22 and S25 devices both fail to play Qobuz content when connected via 5G, but ARC reports no general connectivity issues and can play other content under the same conditions. Qobuz plays fine on your home WiFi.
Forgive the redundancy, but we need two clarifying details:
- do both the S22 and S25 share the same cellular provider? Do you have any different APN settings? You can check in each device by taking the following steps:
- Open Settings: Swipe up from the home screen and tap "Settings".
- Navigate to Connections: Scroll down and tap "Connections".
- Go to Mobile Networks: Tap on "Mobile networks".
- Access Point Names: Tap on "Access Point Names". Are these different between the phones?
- create a hotspot on one device and connect the other device to that hotspot. Can you play Qobuz content under this connectivity configuration?
Thank you again for your patience. We understand this is an arduous troubleshooting process for a key feature of the app. We’ll have a firm grasp of the problem soon.
Hi there
Appreciate the detailed attempt at a diagnosis. In answer to your questions:
- Both the S22 and new S25 share the same cellular provider.
- No issues in navigation or image load for Qobuz on wifi or 5G network.
- Yes, i have been successful with this set up
Glen
Yes, no problem with the Qobuz app under the same conditions.
Thanks for those details, @Glen_Giffen , we’ve added them to your ticket. Please note that your ticket is pending review from the development team, so this may take some time before they are able to look into and address the root cause. Your patienece and understanding is greatly appreciated.
OK, thanks.
I hope this can be resolved in a future update.
Hi @Glen_Giffen,
Thanks again for your patience here. Development has an investigative ticket in the pipeline for a potential fix and will post here as soon as we receive updates from development. We’ll share any workarounds we might uncover in the meantime.
Users who share your cellular network provider have not broadly reported that the Qobuz API fails to buffer content through ARC. Diagnostics indicate that the phone can reach Qobuz servers’, but downloading of the track itself simply doesn’t occur in time for playback to commence. This failure occurs despite strong 5G connectivity reported by the phone’s OS.
The vulnerability could be either:
a) in the upstream pathway to Qobuz’ servers (which we’ve partially probed by comparing a hotspot)
b) An irregularity with ARC’s track download stack or playback engine
We’re investigating both possibilities and will share results accordingly.
In the meantime, please try one more test: disable “Automatically pick best quality” and attempt to play any Qobuz track through ARC whilst connected via 5G.
We’ll watch for your response. Thanks!
Hi Connor,
I have tried switching off “Automatically pick best quality” and the same behaviour persists.
Thanks for your ongoing investigation.
Glen
Thanks for letting us know, @Glen_Giffen , we’ve included this information in your investigation ticket with development. When there are updates to share, we will reach out once more, thanks!
Jumping in to say I have the exact problem as you, on a Pixel 9a that was freshly setup on Android 16. You’re not crazy!
Qobuz works on Wifi, then on cellular a single song will play then things break. Toggling airplane mode will fix it for one song, then it breaks again.
Tidal and local files work AOK.
I previously had an iPhone 13 pro with an identical network config running ARC for years without issue, so this is definitely an issue with the Android app.
Really curious how this goes because all of my music is on Qobuz and this has been quite a annoyance.
Yes, very much hoping for a solution. I note the latest update has seen some improvement. Not perfect, but better
No updates on progress yet @Glen_Giffen but we’ve checked in with our development team to see where things are at. Thanks again for sticking with us here! 
Ok, thanks for remaining in touch.
Not a problem @Glen_Giffen , we’ll let you know once we have more details to share. Thank you in advance for your patience here.
